are you adding it later, when the VM is running? Is it a requirement to do it this way?
You can use oVirt vdsm hook[1] to inject custom snippet to libvirt’s xml on VM startup and
add any channel you want.
It would also allow you to pass arbitrary parameters from oVirt UI, should you ever need
them.

When you attach a compute node to oVirt, it sets up auth with libvirt
to prevent admins from connecting to libvirt. If you want to oiverride
that you need to create yourself a SASL user + password using the
saslpasswd2 command eg see
http://libvirt.org/auth.html#ACL_server_username
